Key result
Respiration-adjusted spectral measures of HRV and the novel BRS(PTT) index correlate well with noninvasive blood pressure measures, providing useful tools for assessing autonomic dysfunction in OSAS.
Why the study?
Do respiration-adjusted spectral indices of HRV and BRS(PTT) accurately assess autonomic dysfunction in patients with obstructive sleep apnea syndrome?
Do respiration-adjusted spectral indices of HRV and BRS(PTT) accurately assess autonomic dysfunction in patients with obstructive sleep apnea syndrome?
Respiration-adjusted spectral measures of HRV and BRS(PTT) may serve as useful clinical tools for assessing autonomic dysfunction in patients with obstructive sleep apnea syndrome.

May support noninvasive autonomic assessment in OSAS; leaves open prospective validation before clinical adoption.
Khoo et al. (2011) studied Obstructive sleep apnea syndrome (OSAS). Respiration-adjusted spectral indices of HRV and BRS(PTT) was evaluated. Respiration-adjusted spectral measures of HRV and the novel BRS(PTT) index correlate well with noninvasive blood pressure measures, providing useful tools for assessing autonomic dysfunction in OSAS.
